High temperatures and strong sunshine will increase the water content in the snowpack. In many areas, the snowpack is melt‑transformed, coarse‑grained, and drains water well, but wet avalanches may still release naturally in exposed terrain. Wet loose avalanches are the most likely avalanche problem, especially on steep, sun‑exposed slopes. Most are expected to be small, but medium‑sized avalanches may occur.

At higher elevations, layering in the snowpack is still present, particularly on north‑facing slopes. With strong meltwater production, water can percolate downward and weaken these layers, potentially triggering wet slab avalanches. These avalanches are difficult to forecast and can be larger than typical loose‑snow avalanches. Glide avalanches may also occur where water accumulates above smooth bed surfaces such as rock slabs. In addition, cornices may weaken and break as temperatures rise.

Høye temperaturer og kraftig sol vil øke vanninnholdet i snødekket. Mange steder er snødekket smelteomvandlet, grovkornet og drenerer vann godt, men våte skred kan likevel løsne naturlig på utsatte steder. Våte løssnøskred er det mest sannsynlige skredproblemet, særlig i bratte solvendte sider. De fleste ventes å være små, men middels store skred kan forekomme.

Høyt til fjells finnes det fortsatt lagdeling i snødekket, spesielt i nordvendte sider. Ved kraftig snøsmelting kan vann trenge ned i snødekket og svekke disse lagene, noe som kan gi våte flakskred. Slike skred er vanskelige å varsle og kan bli større enn typiske løssnøskred. Glideskred kan også forekomme der vann samler seg over glatte underlag som svaberg. I tillegg kan skavler svekkes og knekke når temperaturen stiger.

Snøoverflaten har et tydelig vårlig preg, og det har vært kraftig smelting den siste tiden. Sammenhengende snø finnes fra omtrent 600 moh. og oppover, med lokale variasjoner avhengig av hvor i regionen du befinner deg. Det er mest snø i nordvendt terreng og i indre strøk. Snødekket er i hovedsak smelteomvandlet. Likevel kan det fortsatt finnes noe lagdeling igjen i skyggesider og på de høyeste toppene. Observasjoner viser at det finnes lag av fuktige begerkrystaller ved bakken / dypt i snødekket. Ved rask oppvarming, mye regn eller skavlbrudd kan store skred ikke utelukkes.
